If you are regular foot you will have one heck of an uphill blind spot and need to be carful of running into anyone. If you are goofy foot the blind spot will be more downhill and you can compensate for that more easily by turning your head more. I have a friend who skis with only one eye, but doesn't snowboard because he ran over two people that he couldn't see coming from uphill of him. Your depth perception is going to be off also, although you have probably realized that already :) you will just need to be much more aware of what you don't see and learn to compensate for it.
